[DO NOT MERGE] Don't allow permission change to runtime

Prevent apps to change permission protection level to dangerous
from any other type as this would allow a privilege escalation
where an app adds a normal permission in other app's group and
then redefines it as dangerous leading to the group auto-grant.

Test: Added a CTS test which passes.
